This invention relates to that class of device known as shock absorbers or snubbers' and is designed to provide one that can be easily adjusted and, if necessary, the resili ent member replaced with very little loss of time and at small cost. V

The invention is particularly designed to morelevera e on the free end 24. The bolt 25 and the olt 23 are preferably used for securmgthe lever and the fixed end of the hand, these bolts also acting to strengthen this part-of the support.

L To rovide an even pull on the band for 1ts entlre width the lever is made of two side provide a compressible member usually of pieces asmay be seen from Figure 4, the dis- 60 rubber which is compressed by a band that *tance between these side pieces being approxencircles it or nearly encircles it, which band is, in turn. connected to' a lever at a point intermediate of "its ends, the lever being pivoted at one end and 'connected bya connection, usually flexible, to the axle or a. part associated therewith.

The invention also provides, by this arrangement, a direct pull on the lever and, furthermore, provides for the use of a sin le web or strap which can itself be adjuste as the strap is doubled and is held in adjusted position by a clip.

v The invention is illustrated in the accompanying drawings in which Figure. 1 is a side view of part of a spring and the chassis of an automobile with my im roved shock absorber attached thereto. F1 re 2 is a entral longitudinal section 0 the shock absorber. Figure 3 is a section on line 33 in Figure 2. Figure 4 is a top view of the shock absorber.

In the drawing in order to show the application of the device I have illustrated the axle 10, the spring 11 and the side bar 12 of the chassis of an automobile. The shock absorber is shown at 13 and comprises a sup-.

port or casing, a suitable configuration being usually round and it receives on its outer face a resilient block which is arran 'ed around the support. The form I have il ustrated consists of a support 14 around which is arrangedthe block 15 which is illustrated .m a channel between the flanges 16. The support is secured to the chassis by suitable means such as the bolt 17 and is kept from turnin by suitable means such as.the 18 whlch flank a projectlon on the ChaSSlS.

Arranged around theresilient block '15 is a band 19. usually of steel, fastened at one end as at 20 to the support and fastened at its other end 21 to the lever 22 intermediate of the ends of the lever and preferably near the pivoted end 28 of the lever so as to give imatel the Width of the band 19. The free end o the lever 22 is secured to a connection which extends to a fixed part of the vehicle, which latter is illustrated by the clamp 26 and is shown secured to the axle 10. This connection is usuall in the form of a canvas strap 27 which is ooped around the clamp 26as at 28 and is looped at the other end around the cross-bar 29 at the free end of the lever. These folds are made with the, proper tension and the ends of the strap are fastened against the strap by a suitable clip 30. This provides for an easy and read adjustment of the tension on the strap w en the resilient block becomes slightly compressed but is still usable.

The block 15 is preferably of a size to fit in between the flanges 16 so as to get the full value of the compression of the material. The block or ring 15 is usually made of rubber.

It will be evident that modifications can be made in the arrangement and proportion of the arts without departing from the scope of t e invention.

I claim: c

. 1. A shock absorber for springs comprising a casing with an. annular channel on the outside, an elastic ring in the channel, a band encircling the ring and'secured at one end to the casing, a lever secured at one end to." the casing and near said end'secured to the other end. of the band, and a strand se-' .cured to the free end of the lever.
